Maybe the best benefit of a saltwater hot tub is that you no longer need to store bromine or chlorine tablets. You should still shock the spa, so keep a granular oxidizer on hand, but you can use chlorine-free MPS if you prefer. Spa salt systems make their own chlorine, so it’s still a chlorinated spa. However, the chlorine is created naturally, without binders or additives. It’s pure chlorine.
What ever you call them, when you place enough of them together you do get some power and you will experience a pleasant light massaging effect. Most inflatable spas have somewhere between 100 and 120 bubble jets. That much air does produce some energy. The water fills with air and seems to increase in volume as the bubbles charge towards the surface.
An inflatable hot tub, to state the obvious, is filled with air and air is actually a very very good insulator. Think about double glazed windows. What makes them effective is a layer of air. We have already noted earlier that inflatable hot tubs have thick sidewalls, up to 10 inches thick. This actually provides great thermal protection from heat loss on the sides. Couple this fact with some insulation underneath the hot tub and a decent cover and you have a hot tub that is reasonably well protected from heat loss. Not as good as more expensive models but not to shabby either and one that can certainly be managed.
It is also a relief to know ahead of time the return policy and the manufacturer’s warranties. After all, this is an investment, and you don’t want to throw away your hard-earned money on something that will cause you more stress. You want a nice hot tub to de-stress in after a hard days work, and a reliable product will go a long way in assuring your relaxing time. The Coleman brand is leading the way in portable spas.
